Specific Characters. F<-nmlr. (ieneral form of body about as in L. con- 



genera. L'ostral projection, however. less prominent, and with the tip entire. 

 Lateral expansions of caudal segments well developed and densely spinulose. 

 Caudal rami ahout the length of the anal segment and slightly narrowed distally. 

 Antei'inr antenna' distinctly 7-articnlate. '2nd joint hm-ei- than 3rd. and without 

 any projection hehind. Posterior antennae and oral parts scarcely differing in 

 stiiicture from those in the 2 preceding species. 1st pair of legs, however, with 

 the outer ramus consisting of only 2 joints, the last one twice the length of the 

 1st. Natator\ legs of a >imilar structure to that in tin- ~2 preceding species. Last 

 pair of leijs with the distal joint comparatively small and obtusely truncated at 

 the end. inner expansion of proximal joint short and hroad. not extending to the 

 middle ,,f the distal joint. Ovisac comparatively large, rounded oval in form. 



Mnlr with the 2nd pair of legs much large]- than in female, distal joint 

 of inner ramus shorter than the proximal one. and produced inside to a narrow 

 cylindrical process, finely ciliated on both edges and tipped with a slender bristle: 

 i in front of this process very small and not ciliated. :!nl pair of legs with 

 the inner ramus not transformed, outer ramus. houever. very coarse and incurved. 

 with the spine-, .'-peeialh of the terminal joint, strongly developed. -Ith pair of 

 legs likewise comparatively larger than in female, with the spines ot' the outer 

 ramus stronger and mop- COarselj denticulated. Last pair of legs much reduced 

 in sj/r. and without anv expansion of the proximal joint inside.
